Last week, two days, 5+ hours each, to go through 3 Concourses and 4 Levels of so much information.

SO. MUCH.

Months ago, a friend provided me with the link to register for passes. Thankfully, I took it seriously because as we all know, passes are sold out until next year. However, same day passes are available daily at 9:15am on site at the museum. It's limited, though, and first come-first serve basis. So prepare wisely.
